JOHN WILLIAM PAINE AND CHARLES B. DOUDNA, OF BAYARD, IOWA.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 642,478, dated January30, I900.

Application filed February 2, 1899. Serial No. 704,224. (No model.)

To all whom it may concern-.-

Be it known that we, JOHN NVILLIAM PAINE and CHARLES B. DOUDNA, residingat Bayard, in the county of Guthrie and State of Iowa, have made certainnew and useful Improvements in Acetylene-Gas Generators, of which thefollowing is a specification.

Our invention is an improvement in what are generally known asacetylene-gas generators, and relates particularly to the meansfordischargin g successively a series of charges of carbid into thewater of the generator as well as the provision of means whereby thecarbid is held a short distance below the surface of the water duringthe generating process.

The invention consists in certain novel constructions and combinationsof parts, as will be hereinafter described, and pointed out in theclaims.

In the drawings, Figure 1 is a perspective View of an apparatusembodying our invention. Fig. 2 is a vertical section of the generatingapparatus. Fig. 3 is a cross-sectional view looking up on about line 3 3of Fig. 2. Fig. 4: is a top plan view of the generator, and Figs. 5, 6,and 7 are detail views illustrating the escapement device.

The gasometer has a bell A, which rises and falls as the gas-supply isincreased and decreased, as will be readily understood. This gasometeris connected with and receives the gas from the generator B. Thegenerator B has an outer casing 0, having the sloped bottom 0 and thedraw-oft valve C In the casing O is supported the stand D, which is openat its lower end and dips at such end in the water within the casing O.The stand D is closed at its top and is arranged to revolve within thecasing, it being turned by the stress of a weight E, whose cord E issuitably guided and operates upon a pulley D, which is connected withthe stand D. The stand D is journaled at its upperend in a cross-bar F,which is connected with the casing and extends above the top of thestand. This bar F is detachably connected at one or both ends, so thatit can be adjusted to permit the removal of the stand.

WVithin the stand we provide a series of pockets or cups which arepreferably arrangedin a circular series and have their bottoms arof thebottoms G are released. To secure the bottoms G we provide latches H,preferably in the form of turn-buttons, as shown in Fig. 3, which arepivoted between their ends, are arranged at their outer ends to lapunder the inner edges of the bottoms and hold the same closed, and havetheir inner ends arranged to successively engage and be released by anabutment H, which is fixed with relation to the case 0 and is preferablysecured to the stand-pipe 1, arranged within the generator, as shown inFig. 2. The pipe I is braced in the generator by the inclined rods(shown in Fig. 2) and is provided between the generator and thegasometer with the U-shaped drip-pipe. (Shown in Fig. 2.) As the stand Dis turned its pockets will be successively discharged by the contact ofthe buttons H with the abutment H. If the stand were free to revolveuninterruptedly by the action of the weight E, the several pockets wouldbe discharged in quick succession one after the other; but it is ourpurpose to discharge the said pockets as needed, and to this end wecontrol the movements of the stand by an especial form of escapement,which in turn is operated by the movements of the bell A of thegasometer. To this end we provide on the stand A a series of pins J, onefor each of the pockets G, and we also provide the escapement-lever K,which is pivoted at K to the cross-bar F and is connected at one end bya suitably-guided cord L with the bell of the gasometer and is providedwith the dogs 1 and 2 for engagement with the pins J of the stand D.

In operation when the parts are in the position shown in Fig. 1 one ofthe pins J will lie against the dog 2, as indicated in dotted lines,Fig. 7. If now the gas in the gasometer be consumed and the bell Alowered sufficiently to tilt the lever K to theangle shown in Fig. 6,the pin J, which rested against the dog 2, will be released and thestand D will be given a partial rotation until the next pin J strikesagainst the rear side of the dog 1, as shown in full lines, Figs. 7 and6, and will be held until the bell A rises and permits the lever K toadjust to the position shown in Fig. 5, where the pin J will lie againstthe dog 2 until the operation before described is repeated. As each pinJ is released in turn the stand D is given a partial rotation suflicientto secure the discharge of the contents of one of the cups into thewater. Thus the supply of the generating material is controlled by theconsumption of the gas in the gasometer.

Within the generator we provide a grate M, just below the normalwater-line and in position to receive the carbid discharged by thetripping of the latches which hold the bottom of the pockets.

The gas enters the pipe I from the generator through a suitable openingnear the upper end of the said pipe.

Having thus described our invention, what we claim, and desire to secureby Letters l atent is- 1: The combination of the revolving stand, havingthe projecting pins, the pivoted lever provided on opposite sides of itspivot with dogs moving alternately into the path of the pins, andpockets carried by said stand and arranged to discharge substantially asset forth.-

2. The combination of the generator-casing, the stand revolving thereinand provided with the series of pockets to discharge their contents, thestand-pipe in the generator and supporting the stand at its upper end,and means for operating the stand and for controlling its movementssubstantially as set forth.
